An optimization study of food products is important to be able to develop a nutritious and least costly product using the most efficient processing method. In this study, optimization of an oven-roasted peanut product was done. A two-factor factorial experiment with three levels of garlic solution (4,6, &8 w/w) and roasting time (40, 45 & 50 min) was conducted. Consumer acceptance test and specturm descriptive analysis were done using the 9-point Hedonic scale and 15-cm semi-structrued line, respectively. Roasting time had significant effects on all sensory parameters studied. Garlic level significantly affected fracturability. The optimum combination of 4-8% (w/w) garlic solution and below 47 min roasting time produced a product with acceptability scored of >6.50. Verification study showed the predictive ability of the model which implies that the processor has confidence to choose any combination from the above-mentioned values. Product quality specifications and intensity for color, garlic aroma, hardness, crunchiness, fracturability, toothpacking, saltiness, garlic taste, bitterness taste, peanutty taste and roastedness flavor were established.

Recommendations for consuming industrialized whole grain foods have been encouraged. The present study produced new functional foods and sought to identify the sensory profile of the foods processed. Four types of dried spaghetti were manufactured with different formulas, regarding their whole grain flour and linseed content (10 and 20%). For evaluation of the products obtained, the following methods were employed: sensory analysis of acceptance using a 9-point hedonic scale, applied to 50 trained judges, and Quantitative Descriptive Analysis (QDA) using a 9-cm unstructured line scale. Results were analyzed by ANOVA and Tukey’s test at 5% significance, and the sensory profile was expressed in the form of a spider graph. Acceptance test revealed no difference between the pasta containing 10% and 20% of whole grain and 10% of linseed. Results indicate acceptance of the 20% whole grain product regarding its raw texture and consistency when cooked, in addition to the possibility for the manufacture and acceptance of 10% linseed spaghetti.

Beverage strategies with balanced carbohydrate and protein supply are important for athletes’ recovery. Cow’s milk with added bioactive compounds present in coffee and cocoa facilitates glucose metabolism and may help post-workout glycogen recovery. Home-prepared beverages are cost and nutritionally effective strategies. Thus, the objectives were: (1) To develop home-prepared beverages containing nonfat powdered milk and sugar combined with filtered coffee or cocoa powder in balanced amounts for recovery after endurance exercise; and (2) to perform sensory analysis. Sensory evaluation was conducted by an acceptance test, applying nine-point hedonic scale and descriptive analysis, using the check-all-that-apply method (CATA). McNemar’s test and logistic regression with the proportional odds model were employed. The sample included 44 triathletes and 56 runners, of both sexes, 31–70 years old. Both beverages were well accepted by runners and triathletes, with higher acceptance of the coffee beverage (odds ratio coffee vs cocoa 5.232, p=0.0038). There was no significant difference between acceptance of triathletes and runners for the two beverages. The descriptive sensory analysis (CATA) resulted in slightly different characterizations between the two beverages. Both beverages were well accepted and characterized by the athletes, who can supply different options of post-workout beverages according to individual tastes, composition, and characteristics.

Roasting can increase the Maillard reaction and caramelization of sweet potatoes to create an attractive appearance, color, aroma, and taste, and is rapidly increasing in the commercial market. This study mainly analyzed the influence of roasting sweet potatoes, with and without the peel, on sweet potato quality and flavor characteristics combined with sensory qualities. The results showed that the a* value (1.65–8.10), browning degree (58.30–108.91), total acidity (0.14–0.21 g/100 g, DW), and maltose content (0.00–46.16 g/100 g, DW) of roasted sweet potatoes increased with roasting time. A total of 46 volatile compounds were detected and 2-furanmethanol, furfural, and maltol were identified as the main sources of the aroma of roasted sweet potatoes. A sensory evaluation based on a comprehensive nine-point acceptance test and descriptive analysis showed that roasting for 1 to 2 h resulted in the highest acceptance score (6.20–6.65), including a golden-yellow color, sweet taste, and fibrous texture. The sweet potatoes became brown after roasting for 2.5 to 3 h and gained a burnt and sour taste, which reduced the acceptance score (4.65–5.75). These results can provide a reference for increased quality in the food industry production of roasted sweet potatoes.

Some honey samples from different areas were studied for sensory properties. A panel consisting in 15 trained tasters, identified, defined and evaluated 10 samples of honey, using Quantitative Descriptive Analysis method. The most important sensory parameters, which grouped the samples, were flowery, fruity, body. Two groups of honey consumers one consisting in children aged between 4 and 10 years old the other one in people between 40 and 70 years old were investigated using typical preference scales. The young consumers like the sweet taste, the color and are interested on the package. Another ones appreciate the flowery, fruity notes and the color. Both would like some fruits (nuts, berries…) or pollen in honey.

The objective of this work was to study the effect of the addition of polyphenolic peanut skin extracts (PSE) and oregano essential oil (OEO) on the microbiological, chemical, and sensory properties of frankfurter-type sausages during storage. Seven treatments were prepared: control sample (C: without additives); sausage with commercial additives (F); with OEO (O); with Runner PSE (R); with Virginia PSE (V); with OEO and Runner PSE (OR), and with OEO and Virginia PSE (OV). Consumer tests and general composition analysis were performed on the fresh products (sausages without storage). Sausages were stored at 4 °C during 37 days and samples were extracted at days 0, 12, 23, and 37 for microbiological, chemical (peroxide value and conjugated dienes), and sensory descriptive analysis. All sausages had low fat content (3.36 g/100g) and good colour, flavour and texture acceptance scores by consumers (between 57 on a 9-point hedonic scale). The absence of commercial additives (nitrite, nitrate, and other compounds) affected the sausage characteristic colour, reducing the consumer’s acceptance. The treatments with natural additives had less microbiological and chemical deterioration compared to control sample. The results suggest peanut skin extracts and oregano essential oil can replace commercial additives as preservatives in sausages.

Objective: Ugali is an important meal in many parts of Eastern and Southern Africa and is typically prepared from a single staple food like maize, cassava, millet and sorghum or their composite. The objective of this study was to understand the perception of sensory parameters when varying ratios of maize (refined and unrefined) and sorghum flour when substituted with high quality cassava flour (HQCF) 80%, 60%, 40% and 20% in the preparation of ugali. Methodology: The samples of ugali prepared were randomly subjected to panelists to evaluate sensory attributes preferred most by panelists. Thirty semi trained panelists who were females and males aged above 18 years participated and gave information on sensory signals. The panelists evaluated the samples independently and recorded the rating of the samples in the sensory evaluation questionnaire. The sensory parameters of ugali assessed were color, cookerbility, taste, texture, aroma and general acceptability using a five point hedonic scale. Results: Ugali made from the blends of unrefined maize flour (Dona) and HQCF as well as sorghum flour and HQCF at the ratio of 20:80 and 20:80 respectively were highly acceptable by panelists (mean score < 3). Ugali made from refined maize flour (Sembe) blended with HQCF at ratio of 80:20 was also preferred by panelists (mean score < 3) as compared to ugali made from other ratios. The highly acceptability (mean score < 3) of the ugali was influenced by color, cookerbility, taste, texture, aroma. At these flour ratios the blends of flours resulted in increment of protein, fats and slightly decrease in starch content. Conclusion: Blending HQCF and cereals (sorghum and maize) flours improved the organoleptic and nutritional properties of ugali.

One type of coastal plant in the mangrove forest is the pedada (Sonneratia sp.). This fruit has high nutritional value and has the potential to be processed into food products. This fruit is still rarely used because of its sour taste. One form of food processed from pedada fruit is pedada juice drink. The purpose of this study was to describe the acceptance of the parameters of color, aroma, texture, taste, and overall acceptance in the form of selecting the best formulation, which was analyzed using the exponential method of pedada fruit juice drinks. A descriptive analysis within the experimental design was applied in this research. There were 5 samples in this study, namely A1 positive control (200 g, 70% sucrose sugar), A2 negative control (200 g pedada, 0% stevia sugar), A3 (200 g pedada, 9% stevia sugar), A4 (pedada 200 g, 18% stevia sugar), and A5 (200 g pedada, 36% stevia sugar). The acceptance test used the hedonic method with 40 consumer panelists aged 17-35 years. This research was conducted in May-August 2020. The manufacture of pedada fruit juice drinks and acceptance testing were carried out at home. The results showed that the A4 sample of 200 g of pedada fruit with the addition of 18% stevia sugar obtained the highest score on the acceptability of pedada fruit juice drinks and overall acceptance. The average results of each color, aroma, texture, and taste acceptability parameter were 3.9, 3.9, 4.0, and 4.0, respectively.

This study aimed to evaluate the effect of sucralose added in Greek Yogurt flavored with araticum (Annona crassiflora) and mangaba (Hancornia speciosa) through sensory characterization. The Greek yogurt was prepared with skimmed milk, inoculated starter cultures, filtered and it was supplemented with the appropriate amount of sucralose, added sweetened and pasteurized fruit pulp (araticum or mangaba). The total phenolic compounds and texture were performed and sensory analyses were carried out by Quantitative descriptive analysis (QDA) and acceptance test in storage for 7 and 28 days. The QDA results showed that the main attributes were color, lightness, creaminess, presence of particles, fullness, and aroma. Eighty percent and 85% of the panelists were said they would buy the araticum Greek yogurt and the mangaba Greek yogurt after 7 days of storage, respectively. Additionally, 71% and 77% were said they would buy the araticum Greek yogurt and the mangaba Greek yogurt after storage for 28 days at 4&ordm;C, respectively. The sensory profile and acceptance test results of the Greek yogurts developed indicated no perceptions caused by adding sucralose to the yogurt after storage for different times. The highest concentration of phenolic compounds in the araticum Greek yogurt was perceived by the panelists in aroma and flavor attributes. Changing sucrose to sucralose was not imperceptible under the storage and consumption conditions.

Children are an important targeted consumer group of food and beverage industry nowadays, especially of dairy industry. Understanding children liking for sensory properties of a food product is the key for product development success. Pasteurised milk and UHT milk are two major choices for children drinking milk in Vietnamese market. The difference in production process of these two products, mostly the heating treatment, may occur differences in terms of sensory properties and by consequence affect children’s preference. The objectives of this study were then i) to verify ability of the 7-point facial hedonic scale in evaluating children preference of different age groups; and ii) to compare the degree of liking of pasteurised milk and UHT milk by children. 240 children aged from 4 to 13 participated to an acceptance test using 7-point facial hedonic scale. One pasteurised milk sample, one UHT milk sample and one UHT sweetened control sample collected from the market were tested. These 3 testing products belong to one local producer. Results showed that for all testing age groups children rated the control sweetened sample as the most favourite. This helps to justify that children of these ages are able to use the scale. There was no difference of children liking for tested pasteurised milk and UHT milk on all testing age groups. Possible sensory difference between these products is not resulted in preference differences among the testing children. Further results on the effect of age group, gender and general milk liking of children were also discussed.

Goat cheeses from high heat treated milk (HHTM: 80 °C/5 min (E1) and 90 °C/5 min (E2)), could be regarded as new products, compared to their analogues made from commonly pasteurized milk (65 °C/30 min (C)). Descriptive analysis and consumer tests with a hedonic scale and JAR scale were part of the product development process. The use of scanning electron microscopy enabled deeper insight into the flavor and texture of the cheeses. In all cheese variants, goaty flavor was mildly pronounced. Young HHTM cheeses also had a pronounced whey and cooked/milky flavor. Consumers found such flavor ‘too intensive’. Unlike the control variant, HHTM cheeses were not described as ‘too hard’. Such improvement in texture was found to be a result of fine, highly branched microstructure, sustained over the course of ripening time and highly incorporated milk fat globules inside the cheese mass. Cluster analysis showed that the largest group of consumers (47.5%) preferred E2 cheese. Although consumers found that most of the cheeses were ‘too salty’, this excess did not decrease their overall acceptance. Neither microstructure analysis nor descriptive sensory analysis of goat white brined cheeses produced from high heat treated milk has been done before.
